Definitions

  • the invention relates to heat exchangers and more precisely an inlet arrangement for a plate heat exchanger.
  • Plate heat exchangers of various designs have been used in cooling and heating installations for a long time and are advantageous for various reasons. For example, they are compact and have a large heat exchanging surface with respect to the volume and space needed.
  • US 6,702,006 suggests an inlet arrangement for a plate heat exchanger where the openings in the channel have a varying design to improve the distribution of media over the plates. With this arrangement, the distribution is improved by changing the direction of the flow of a part of the media and pushing it towards the openings in the channel on a cated plate. This arrangement does not establish a liquid surface or make use of gravitational forces as suggested by the present invention. This arrangement will not function in a desorber/absorber where the liquid/gas fraction is very small.
  • Fig. 1 shows the top in cross section of a plate heat exchanger, seen from the side, with an inlet arrangement according to the invention
  • Fig. 2 shows the top of the plate exchanger of fig. 1 with the inlet arrangement seen from the inlet
  • Fig. 3 shows a cross sectional view of the inlet arrangement during operation, with an indication of the level of liquid
  • Fig. 4 shows a top in cross section of a plate exchanger, seen from the side, with an inlet arrangement according to another embodiment of the invention
  • Fig. 5 shows a sectional view of an adjustable inlet arrangement according to the invention.
  • Fig. 6 shows the lower part in cross section of a plate heat exchanger, seen form the side, with an inlet arrangement according to a third embodiment of the invention.
  • the invention relates to an inlet arrangement 1 for use in plate heat exchangers 2 as shown in the figures.
  • An object of the arrangement is to create a liquid surface at the lower part of the inlet channel in the exchanger so that gas and liquid is distributed more evenly through all the ducts of the exchanger.
  • Figure 1 shows the cross section of a part of the plate heat exchanger 2 where an inlet arrangement 1 according to the invention is mounted.
  • the plate heat exchanger 2 comprises plates 3 designed to create a plurality of ducts 4 between the plates 3.
  • the ducts 4 are arranged in two or more groups so that the different media can flow in separate streams through the 5 plate heat exchanger 2.
  • the plurality of plates 3 form a substantial heat exchanging surface and provide a good exchange of heat between the different media without any great demands for space for the heat exchanger.
  • the arrangement 1 comprise ao flexible steel plate or a rigid pipe which is introduced into the inlet 5 in a plate exchanger ready for use to create a cylinder wall with a longitudinal opening or slot 6.
  • the plate is preferably long enough to cover all of the inlet depth.
  • the breadth of the plate is adjusteds so that the longitudinal opening or slot 6 is created in the longitudinal direction of the inlet 5.
  • the size of the slot 6 and thereby the size of the plate can be adjusted in each case and to different designs and sizes of the plate heat exchanger.
  • the inlet arrangement 1 comprises two overlapping plates 1, 7 which can be shifted versus each other in order to change the size of the slot 6.
  • the width and orientation of the slot 6 can, according to5 one embodiment, be regulated automatically by rotating the inlet arrangement by means of a suitable driving device, such as a motor, controlled for example according to measured temperature distribution between the plates.
  • a suitable driving device such as a motor
  • the inlet arrangement is preferably made of a resilient material.
  • the pressure drop in the structure contributes to pressing the material towards the heat exchanger plates 3, and gives an improved tightening at the slot 6 and ends to prevent liquid from entering .
  • the angular orientation of the slot 6 (preferably between approx. 20° and 45°) and the width of the slot 6 can be adjusted to capacity and/or quantity and the design of the plates 3.
  • Several different duct patterns for plate heat exchangers are commercially available and the width and orientation must therefore be adjusted accordingly.
  • the orientation of the plate exchanger 2 relative to the vertical plane will also influence the distribution of gas and liquid through the ducts 4 of the exchanger. It can therefore be advantageously to adjust the orientation for an improved productive capacity. It has been found through experiments that the angle should preferably be between 88° and 92° in relation to the horizontal plane. The optimal angle can be found by measuring the temperature distribution between the plates 3. The practical angle is defined by geometry and gas/liquid velocity. To obtain approximately the same effect, the slot 6 of the inlet arrangement can be oriented inclined in relation to the horizontal plane.
  • angle of the plate exchanger also can be regulated automatically in relation to the temperature distribution over the exchanger, for example by means of a suitable control unit with an associated motor operator.
  • the inlet arrangement has a sharp edge 9 along the slot. This edge will create turbulence and efficiently mix gas and liquid and accordingly improve the distribution.
  • the sharp edge can be supplied with triangular recesses 10 (like a V- groove) to create a V- shaped overflow edge securing a minimum level of liquid in each duct 4 when the level of liquid rises above a minimum.
  • the inlet arrangement has a tubular design and is attached to one or both ends of the inlet.
  • the inlet arrangement according to this embodiment has a diameter which is smaller than the diameter of the inlet and will therefore not completely seal the inlet. However, the opening of the inlet arrangement will abut on the inlet.
  • One end of the inlet arrangement is placed towards the back wall or is sealed by a plate. This embodiment is suitable when the plate exchanger is a bubble absorber. The gas enters the inlet arrangement and the liquid enters adjacent thereto.
  • the inlet arrangement 1 according to the invention in some cases triples the heating/cooling output for plate heat exchangers used as absorbers/desorbers .

Abstract

L'invention présente un agencement d'orifice interne (1) destiné à être utilisé dans des échangeurs de chaleur en plaque (2). L'agencement comprend un élément avec une ouverture de dispersion (6) pour l'agencement dans un orifice interne (5) d'un échangeur de plaque. L'agencement d'orifice interne (1) est organisé pour former une paroi cylindrique relativement adaptée lors de son introduction dans l'orifice (5). La paroi cylindrique comprend au moins une ouverture (6) qui s'étend partiellement ou entièrement le long de la longueur de l'orifice (5) et qui est agencée de manière étanche en direction de l'orifice (5) de l'échangeur de chaleur en plaque. De plus, l'orifice (6) est orienté en direction d'un des côtés formant un angle depuis le perpendiculaire. L'utilisation d'un tel agencement d'orifice (1) est également présentée.
